BATH-TUB.

SPECIFICATION forming part of Letters Patent No. 476,950, dated June 14,1892.

Application filed January 13,1892. Serial No. 417,988. (No model.)

To all whom it may concern.-

Be it known that I, JAMES T. WATSON, a citizen of the United States, anda resident of the city of St. Louis, in the State of Missouri, haveinvented a new and useful Improvement in Bath-Tubs, of whichthefollowing is a specification.

My invention relates to water and vapor bath-tubs; and the object of thesame is to combine the advantages of water, vapor, and heat arising fromsimple or medicated liquids in one bath.

The invention consists in the combination and arrangement of partshereinafter de scribed and claimed.

I attain the object by the mechanism illustrated by the accompanyingdrawings, in which- Figure 1 is an elevation of my bath-tub with a partof the outside shell cut away. Fig. 2 is a vertical section drawn on theline 2 2,I ig. 1.

A is an outside shell, which may be cylindrical in shape and serves tosupport the up per portion of the tub, as well as confine the heat andgases generated by the lamp B. This lamp B is an ordinary lamp adaptedto burn alcohol or other combustible substance, which may or may not bemedicated. This outside shell A is provided with holes it near the top,and through which the heat and gases from the burning lamp I3 can escapeand, mingling with the vapor from the water, come in contact with theskin of the person sitting in the tub.

O is a metallic partition arranged within the outside shell A and ismade concave on its upper side, whereby it is adapted to hold water orother fluid to be used in the bath. Above this partition 0 is anotherpartition D, which unites with the walls of the partition 0, thusforming a reservoir F for water and vapor between the two walls of thepartitions O and D and a basin H above the partition D. The upperportion of the partition D around the periphery is provided with holes hto allow the vapor from the water in the reservoir F to escape. At thebottom, near the center of the partition D, there is preferably a holeE, which allows a free communication between the bowl formed by thepartition D and the reservoir between the partitions 0 and D. Throughthis hole the water will pass and have free communication with the waterin the reservoir F. \Vhen itis desired to have the water in the basin Ha differenttemperature than in the reservoir F, the plug P can beinserted in the hole E. This is provided with a reservoir drain-cock G,which passes out through the outside shell A and which serves to drainthe water from the reservoir F. By the construction of the twopartitions O and D,I am enabled to maintain a water-cushion interposedbetween the body of theperson using the tub and the fire, which preventsany danger of being burned. hen a person desires to take a bath, hethrows a covering over his body, drawn tight around the neck, and sitsdown in the water of the basin, letting the blanket fall over thebathtub, so as to confine the vapor and gases, and puts the lighted lampunderneath.

Now what I claim, and for which I ask Let ters Patent to be granted tome, is

In a batlrtub an upper partition concave on its upper surface and convexon its lower surface and supported on the body of the bath-tub and alower partition arranged below said upper partition, said partitionsbeing joined together at or near their peripheries and provided withvapor-holes and forming a reservoir for the reception of water, for thepurposes specified.
